Flash Cache?

Does anyone know how Flash animations are cached on a user's computer? I've found that sometimes when I upload a new version of a flash file to a web site, it will refuse to update, even if I completely empty the browser cache and refresh the page. Sometimes even opening a different browser doesn't help. The problem only occurs if I've already viewed the animation recently, and it doesn't always occur.

A bunch of other people at my work have had the same problem, and it leads me to wonder if Flash caches some files outside of the browser cache. Does anybody know anything about this?

Now, what you can do is send flash a random querystring value when it's embedded. This can be done either through server-side or client-side, but it should definitely be a random value. So for example, a view source might output something similar to the two lines above, only appended with a querystring value
